Perhaps it may be a good idea for me to update the next release as follows:
A dropdown list or radio group is populated from a lookup array which may be obtained at runtime either from the contents of a database table or from an entry in a language_array.inc file (part of the Internationalisation feature). This array by default contains only non-blank entries, but sometimes a blank entry is required to indicate that no choice has yet been made. This can be done automatically by the framework (using a blank key with a description of "undefined") when the lookup array is loaded into the XML document. Blank entries are NOT required in multi-choice dropdown lists, so the framework needs to check the control type of the field before it knows whether to insert a blank entry or not. The name of the lookup array need not be the same as the field into which that array will be loaded, so the framework will function as follows:
(a) If the lookup array has the same name as a field on the current screen, then it will be assumed that the array belongs to that field.
(b) If the lookup array does not have the same name as a field on the current screen then the framework will step through the contents of $fieldspec until it finds the entry where "optionlist" contains the name of that lookup array.
Will this be sufficient?
